Surah Al-Baqarah, Verse 93

وَإِذۡ أَخَذۡنَا مِيثَٰقَكُمۡ وَرَفَعۡنَا فَوۡقَكُمُ ٱلطُّورَ خُذُواْ مَآ ءَاتَيۡنَٰكُم بِقُوَّةٖ وَٱسۡمَعُواْۖ قَالُواْ سَمِعۡنَا وَعَصَيۡنَا وَأُشۡرِبُواْ فِي قُلُوبِهِمُ ٱلۡعِجۡلَ بِكُفۡرِهِمۡۚ قُلۡ بِئۡسَمَا يَأۡمُرُكُم بِهِۦٓ إِيمَٰنُكُمۡ إِن كُنتُم مُّؤۡمِنِينَ٩٣

wa-idh akhadhnā mīthāqakum warafaʿnā fawqakumu l-ṭūra khudhū mā ātaynākum biquwwatin wa-is'maʿū qālū samiʿ'nā waʿaṣaynā wa-ush'ribū fī qulūbihimu l-ʿij'la bikuf'rihim qul bi'samā yamurukum bihi īmānukum in kuntum mu'minīna

And [recall] when We took your covenant and raised over you the mount, [saying], "Take what We have given you with determination and listen." They said [instead], "We hear and disobey." And their hearts absorbed [the worship of] the calf because of their disbelief. Say, "How wretched is that which your faith enjoins upon you, if you should be believers."
